How do we get Serratia infection?

The major factors that are involved in the development of the Serratia infection include contamination of the respiratory equipment and poor catheterization techniques. Most of the outbreaks have been reported from the paediatrics ward.

Do healthy people get Serratia?

They do not cause infections in healthy individuals, but therapies, conditions, and procedures that compromise patients immunologically or physiologically make them susceptible to colonization by opportunistic pathogens, including Serratia. Infants, very old patients, and intravenous drug users are also susceptible.

How is Serratia transmitted?

MODE OF TRANSMISSION: Ingestion of contaminated foods and direct contact 3. Nosocomial transmission may occur by hand contact from hospital personnel and other patients. Fomites may also spread Serratia. INCUBATION PERIOD: Unknown.


How does Serratia marcescens enter the body?

marcescens infections are known to be transmitted through hand-to-hand contact by medical personnel. In this case, solutions used for medical purposes, catheterizations, and needle punctures can be contaminated and infect patients(31). Patients may also be infected with S.

Where is Serratia marcescens commonly found?

Serratia marcescens is commonly found in the environment, particularly in consistently damp conditions where the bacteria grow rapidly. S. marcescens can frequently be seen on tile and shower corners or at the water line of a toilet bowl where it appears as a pink or orange filmy residue.


Osmosis | Serratia Marcescens



What is the most likely mode of transmission for healthcare associated Serratia infections?

It is associated with urinary and respiratory infections, endocarditis, osteomyelitis, septicemia, wound infections, eye infections, and meningitis. Transmission is by direct contact.

Can Serratia be cured?

Serratia infections should be treated with an aminoglycoside plus an antipseudomonal beta-lactam, as the single use of a beta-lactam can select for resistant strains. Most strains are susceptible to amikacin, but reports indicate increasing resistance to gentamicin and tobramycin.

Where does Serratia marcescens bacteria come from?

The bacteria will grow in any moist location where phosphorous containing materials or fatty substances accumulate. Sources of these substances include soap residues in bathing areas, feces in toilets, and soap and food residues in pet water dishes.

At what site is Serratia normally found?

It is commonly found in the respiratory and urinary tracts of hospitalized adults and in the gastrointestinal systems of children. Due to its abundant presence in the environment, and its preference for damp conditions, S.


How do you prevent Serratia marcescens infection?

The best way to minimize the potential risk of suffering harm from Serratia marcescens include: Thorough Cleaning – A thorough cleaning of all kitchen and bathroom surfaces along with the pet's water bowl is necessary by scrubbing the surface where any fatty or phosphorus substances have accumulated.

Is Serratia marcescens airborne?

Since Serratia marcescens is airborne, it's possible that you might notice more pink slime around your home during warm weather when your windows are open. Or, if you use a water filter that removes chlorine, you might find that your sinks, bathtubs and toilets are more hospitable to the bacterium.

How do you get rid of Serratia marcescens in the air?

Bleach. Bleach can be used for mold and Serratia marcescens. If you opt for this course of action, make sure you have good ventilation in the room, and never mix bleach with vinegar or ammonia as it can cause toxic fumes.

What body systems does Serratia marcescens affect?

S. marcescens can infect numerous sites including urinary,16 respiratory,17 epithelia, muscle and subcutaneous tissues.


What happens if Serratia marcescens is left untreated?

marcescens has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia.

Is Serratia normal flora?

Serratia species are gram-negative bacilli of the Enterobacteriaceae group of bacteria, although they are not a common component of healthy human fecal flora.

How common is Serratia marcescens infection?

While S. marcescens is a rare cause of community-acquired infections, it has emerged as an important nosocomial healthcare-associated pathogen and a frequent source of outbreaks of hospital infection (72), in both adult (122) and paediatric patients (115).

Can Serratia cause UTI?

Approximately 30-50% of patients with Serratia urinary tract infections are asymptomatic. Symptoms may include fever, frequent urination, dysuria, pyuria, or pain upon urination. In 90% of cases, patients have a history of recent surgery or instrumentation of the urinary tract.


What disinfectant kills Serratia marcescens?

Though Serratia will not survive in chlorinated drinking water, the bacteria can grow in toilets where water is left standing long enough for the chlorine to dissipate. To kill the bacteria, clean affected surfaces with a strong chlorine bleach solution.

Can Serratia cause pneumonia?

Patients with Serratia respiratory tract infection are usually are colonized with Serratia species after instrumentation (eg, ventilation, bronchoscopy), especially those with chronic obstructive pulmonary disease. Serratiapneumonia may develop, but this is rare.

What causes Serratia marcescens in shower?

The discoloration comes from a biofilm—that is, a bacterial colony—of Serratia marcescens. The airborne bacterial species thrives in moist environments like showers, where it feeds on mineral deposits in soap scum and fatty deposits in soap and shampoo residue.

What causes a pink ring in the toilet bowl?

However, the pink ring that develops at the water line in the toilet, around drains, in the tub/shower area, in bathroom drinking cups, and even dog bowls is actually caused by airborne bacteria known as Serratia Marcescens.


What causes Serratia marcescens in toilet bowl?

Serratia marcescens love a moist environment but cannot survive in chlorinated water. However, when tap water sits around, like in a toilet bowl, or on grout, or on a shower curtain, the chlorine evaporates and bacteria can take root and multiply, especially if soapy deposits are present which they use as food.

How do you grow Serratia marcescens?

Serratia, like other Enterobacteriaceae, grow well on ordinary media under anaerobic and aerobic conditions. They grow well on synthetic media using various compounds as a single carbon source. Optimum growth of all strains of Serratia has been observed at pH 9 and at temperatures from 20–37°C.

How can you tell the difference between Serratia marcescens and E coli?

The key difference between E coli and Serratia marcescens is that E. coli is a coliform bacterium that belongs to genus Escherichia and is a part of normal gut flora while Serratia marcescens is a gram-negative rod-shaped bacteria which has the ability to produce red colour pigment at the room temperature.

Which body site harbors the greatest number of bacteria?

The small intestine usually contains small numbers of streptococci, lactobacilli, and yeasts, particularly C. albicans. Larger numbers of these organisms are found in the terminal ileum. The colon is the major location of bacteria in the body.
